Final answer:
The transportation of oxygenated blood and nutrients throughout the body's cells is handled by the process of circulation, which is facilitated by the circulatory system involving the heart, blood vessels, and blood.
Step-by-step explanation:
The process involved in the transport of oxygenated blood and nutrients throughout the cells is c) Circulation. The circulatory system is responsible for delivering oxygen and nutrients to the body's cells and tissues, as well as for removing carbon dioxide and waste byproducts of respiration. Nutrients absorbed in the digestive tract are processed in the liver and sent to cells via the bloodstream, while oxygen is obtained through respiration in the lungs and circulated by the heart. The blood is the medium for this transportation, carrying hormones from endocrine glands to target cells and removing cellular wastes to excretory organs like the kidneys and liver.
